A clean room is a room where the concentration of particles is minimized. Temperature, humidity and pressure parameters are also controlled.
Operators use particular clothes (foot booties, coat, hairnet and gloves) to avoid dirtying the room.
Clean rooms are used for the industry or research fields, which are sensible domains to environmental contamination (biology, construction of spacecraft, optical manufacturing or semiconductors…).
To cope with rising demands of optics and space applications, an ISO 7 (class 10 000) clean room has been installed to minimize the presence of particles such as dust to enable the integration of “clean” and vacuum compatible hexapods.
In the space sector, we regularly deliver ISO 5 compatible systems, for which we follow the design and assembly rules related to the cleanliness of the ISO 5 environment.
